Bus Rapid Transit
I am currently taking a six month 'career break' and have based myself in Bangkok. There is much to share about the assorted public transport in Bangkok but I am going to start with its single bus rapid transit (BRT) system. The success of BRT in cities in south America (Curitiba and Bogota being the oft quoted examples) has seen the promotion of such systems in the developing world, in central Africa and the Far East. My recent travels give me three operating BRT systems to write about, as well as the scheme under construction in Vientiane in my previous post.
Overview
Bangkok BRT is a single route that has been in operation since 2010. It connects (in a fairly vague sense of the word) with the rail based rapid transit at both ends: to the east at Chong Nonsi station on the BTS Skytrain, and at the west Talat Phlu on the MRT subway. However, as is common in Bangkok the BRT stations carry different names (in this case, Sathorn and Ratchapruek are the corresponding BRT station names.)
The basic concept is similar to more developed systems, running in dedicated lanes on the off-side of the carriageway and island platforms. This necessitates vehicles with passenger doors on the off-side rather than the near-side. The island stations located along Bangkok's busy highway system necessitates access by footbridge (solely; there are no tunnels). The station concept is not dissimilar to
my previous experience on Cape Town BRT.
There have been questions about the longevity of Bangkok's BRT over it's fifteen year life: low ridership possibly being a factor of Bangkok's local buses often being surprisingly rapid despite the traffic levels, and the relatively low BRT frequency of every 10 minutes negating any in-vehicle time savings.
There have clearly been fundamental changes to the operating concept for Bangkok BRT since it opened:
- Ticket offices: every rail/metro station has staffed ticket offices, and Bangkok BRT was built with these as well at every station. However they are now all closed;
- Ticket gates and off bus ticketing: evidently the system was designed as 100% off bus ticketing and now every Bangkok BRT station has decommissioned ticket gates. Ticketing is now flat fare paid on board the bus;
- Fares: it appears that there has been very lacklustre policing of ticketing, as every station has posters informing customers that the flat fare, 15 baht (around 35 pence) will be charged from 2024.
However the biggest change as been the switch from boarding high floor buses from platforms (like Curitiba, Cape Town q.v) to using low floor buses. In 2024 a new fleet of electric buses built by CRRC (China) entered service and these are of a typical modern low floor design. However this is incompatible with the high floor platforms, so at the end of every platform, a checkerplate ramp to ground level has been constructed, and new stop locations for the bus beyond the platform.
At the time of my visits to Bangkok BRT in March and April 2025, some of the dedicated BRT lanes were closed to facilitate work on the adjacent banks of the canal that runs between the carriageways. This means that BRT buses have to pull in to general traffic on the off-side, which isn't an easy manoeuvre in general Bangkok traffic where it is 'survival of the fittest/bravest' most of the time.
Stations

Overview of a Bangkok BRT ststion. They are all very similar. Overbridge, with access from street at both ends, and access to platforms in the centre. |
 |
Every station has ticket machines that are no longer used. |
 |
Just as every station has ticket barriers that are no longer used. |
 |
And ticket offices that are no longer used. |
Dedicated Lanes
 |
Bangkok BRT has dedicated lanes for the majority of the route. Towards the west they tend to be designated with road markings. |
 |
Towards the east they tend to have a physical segregation from general traffic. |
 |
Embankment work on the adjacent canal towards the east end of the route meant that the BRT lane was closed. The physical segregation has been lifted and buses merge in to general traffic. |

BRT bus merging in to general traffic. On this Saturday afternoon photograph traffic was quite light. At the next station the alignment of the barriers would allow the bus to move back to its dedicated lane to serve the station. |
Boarding
 |
The Sathorn terminus has this air conditioned in door platform. This is a great facility at what should be one of the busiest stations with the interchange to the Skytrain. |
 |
However the platform is bult for high-floor level boarding. The access the current low floor buses customers must exit the platform, and go down these steps to access the bus. |
.
 |
The paving at the revised stop is variable depending on what was therefore. Often it's just some bitumen filling gaps. There is no effort to provide a suitable kerb (or similar) for boarding, resulting in a fairly high step. |
 |
This is a typical layout of the boarding area at Bangkok BRT stops. The platform for the original high floor vehicles has had a surface level access added, in this case a ramp. |
 |
The original bus stopping location s shown by the yellow and red stripes: behind that can be seen the yellow surface paint showing where the new low floor buses stop. |
 |
This is the Ratchapruek terminus at the west end. Where once there was steps up to the platform (buses stop on the far side), there is now a ramp down t walk round the station building to access the BRT bus. |
 |
As is the norm, there is no attempt at Ratchapruek to provide any kind of kerb to ease boarding the BRT buses. |
Vehicles
 |
Since late 2024 Bangkok's BRT (route 462) has been operated by these electric buses manufactured by CRRC of China. Whilst the offside door for BRT operation is visible, they have also been built with nearside door allowing for use on conventional bus routes. However this won't happen imminently as the BRT is operated by BTS (hitherto operators of some of the elevated rail and monorail routes in Bangkok) and regulated by the MRTA - Mass Rapid Transit Authority of Thailand. This is all separate from municipal bus operations. |
 |
Vehicle interior. Typical modern bus, although they are little over ten metres long which doesn't afford for many seats. There are wheelchair bays despite the inability for wheelchairs to board at many (if not all) stops. |
 |
Other than a Thai bank QR code system (which is both incredibly common in Thailand and totally alien to westerners) the only other way to pay for the 15 baht flat fare is with a 'Rabbit' card, which is a proprietary pre-paid card issued by BTS. There is presumably an assumption that tourists have n need to ever use the BRT as there is no 'visitor friendly' way of paying. For the record I used by pre-paid Rabbit card to travel! |
Concluding
There are many elements to a bus rapid transit scheme and it is very easy to focus on those which are easiest (either in construction, operation or long term funding requirement). In the case if Bangkok this appears to have been the stations where ticket offices, ticket machines and ticket barriers are all now abandoned. Other successful BRT schemes from Bogota Transmilenio to
Istanbul Metrobus have similar, but support either a broad network of routes or a very very high frequency.
The overarching design of Bangkok BRT has been to facilitate a very high frequency service, evidenced by the fact the infrastructure could not be used by any conventional buses. However it has never achieved that and indeed was threatened with closure in 2017. It is therefore not as popular as it could be because the higher frequency of local buses (or commination of local bus routes) on parallel sections allows for shorter wait times.
Beyond the journey time challenge, the latest developments also lead to a very customer unfriendly system. There was originally level access (by lift or stair-lift) to and from tickets halls from both street and platform. Now there is a variable mix of steps to road level, step to bus and miscellaneous kerbs for customers to handle. It is impossible for wheelchairs/pushchairs and difficult for inform passengers. As a rule you have to have a significant journey time advantage to go to the effort of using Bangkok BRT, and it seems few people do.
Why not just buy new buses that could serve the existing platforms? With so many systems requiring these in South America I am sure the likes of
Marcopolo could supply a suitable new vehicle.
Ticketing is equally poor: there is no ticket product available for visitors to Bangkok. Yet the operator, BTS, and scheme promoter, MRTA, own various ticketing systems that allow tickets to be bought for travel on their other metro systems (although, these are all gated and tickets to suit that modus operandi.)
Which leads to the question of what has gone wrong? I think it comes down to 'fashion'. When it was built, bus rapid transit systems were fashionable so there's a degree of 'me too' without a solid business case. Is Bangkok BRT an answer looking for a problem?
Currently electric buses are fashionable (
and Thailand builds them) so again 'me too', even though the products [I assume] available were not fit for the infrastructure.
Scheme development in the Far East also appears to not be subject to the project management/organisational scrutiny of those in the west. I will eventually blog about more schemes where there is a disconnect between planning, design and operations, where there is evidently no (or poor) 'sponsor' or 'integration' functions.
I have some thoughts on the causes of some of these project failures, but one for another day!
